摘　　要：从深度相关性、非对称性、分段性、时间性和复杂性等五个方面,分析了旗山矿深部巷道的底臌特征。运用数值模拟和理论分析等方法讨论了底臌的影响因素,主要包括自重应力、构造应力、地层结构、岩石特性、支护设计及施工工艺等。最后,有针对性地提出了控制对策。现场实施取得了良好的效果。The characteristics of floor heaving are analyzed from five aspects, which include depth--dependent, asymmetry, regional, timeliness and sophisticated. The influencing factors of floor heave are discussed by the way of numerical simulation and theoretical analysis. The key factors mainly include gravitational force, tectonic stress, stratum structure, characteristic of rockmass, support design and construct technology, and so on. The control countermeasures are put forward, which are proved to be effective and successful through engineering practice.
